I’m not a true expert here but my observation is that
IF
(x) you have ample capital, and
(y) want to do something reasonably hard, where you need a whole bunch of very talented, experienced web engineers,
(z) which are impossible to get, especially fast
THEN
(aa) Pivotal Labs is one of the very top places to go.
They’ve created a great culture where lots of high quality engineers go instead of doing a “start-up”. The key is lots. There are a number of boutique shops, but if you need what are really outsourced resources … most boutiques can’t get you enough throughput.
Pivotal Labs can, near as I’ve observed.
You gotta pay, though.
